Arduino senses the environment by receiving inputs from add-on devices such as sensors, and can control the world around it by adjusting lights, motors, and other actuators. In this class you will learn how and when to use the different types of sensors and how to connect them to the Arduino. Since the external world uses continuous or analog signals and the hardware is digital you will learn how these signals are converted back-and-forth and how this must be considered as you program your device. You'll also learn about the use of Arduino-specific shields and the shields software libraries to interface with the real world. Please note that this course does not include discussion forums.

Module 2

This module introduces sensors and actuators and discusses how to interface with them. We’ll examine different classes of sensors and actuators. For each type of sensor/actuator, we’ll examine the circuitry needed to interface with it. Additionally, we’ll take a look at the Arduino code needed to communicate with the sensors and actuators.
